Brake Rotors-Is Rotor Surface Rust a Problem?

Rotor Surface Rust

Is rotor surface rust a problem? Has your vehicle been sitting for a long period and your rotors rusted over?
Most likely it’s nothing of concern. Surface rust will be cleaned off with normal driving.

However, if the rust has gone so far as to cause pitting in the rotor you have a larger issue. This usually takes months of a car sitting. If you drive the car for a while and friction surface, where the pads meet the rotor, looks corroded and pocked instead of smooth and shiny. You rotor will need to be turned or replaced.
